Please add a "Is Empty" selection in Dashboard Parameters to filter for items where that field is Empty.
For example, if Assignee is a parameter, we would like the ability to filter the dashboard to unassigned items, not only items assigned to a specific peron(s).
Please let me know if there are similar requests already out there with more votes, or if there is a workaround for this.
Thank you.
